    Study Notes

    Cholinergic Antagonists

    • Tolterodine is a muscarinic blocker used to relieve urinary and bladder difficulties.

    Cholinergic Stimulation

    • Cholinergic stimulation increases the contraction of smooth muscle, increases the secretion of glands, and increases the peristalsis of the digestive tract.

    Nicotinic Acetylcholine Receptors

    • Nicotinic acetylcholine receptors are found in the autonomic ganglia, the neuromuscular junction, and the central nervous system.

    Ephedrine

    • Ephedrine is not a cholinergic agonist, but rather a sympathomimetic amine.

    Nasal Decongestants

    • The use of nasal decongestants is associated with rebound congestion, also known as rhinitis medicamentosa.
